What's the muffler arrangement on the MKNI0107?

A chambered centre muffler does the main quietening and a free-flowing rear hotdog finishes the system at the tailpipe.

What size is this cat-back?

It's 2.5in, sized to suit the 4.5L engine in the Patrol GU.

Does it keep the catalytic converter?

Yes — it's a cat-back, so it starts behind the factory cat and leaves the converter in place.

The MPI Automotive MKNI0107 is a 2.5in cat-back for the Nissan Patrol GU 4.5L, running a centre muffler and a rear hotdog. The order matters here: the chambered muffler sits in the middle and a free-flowing hotdog finishes at the rear.

Why a centre muffler and rear hotdog?

This layout puts the heavier quietening up front. The centre muffler is a chambered, absorptive unit that does the main silencing through the middle of the car, while the rear hotdog is a compact straight-through resonator that lets the note breathe out the back rather than choking it. On the 4.5L petrol Patrol that gives a controlled tone with a freer exit than a twin-muffler setup.

What does a 2.5in cat-back cover?

A cat-back replaces the exhaust from the catalytic converter rearward, leaving the factory cat and emissions hardware in place. At 2.5in it's sized for the GU Patrol's 4.5L engine, a sensible street bore for a large 4x4 that spends time loaded or towing rather than chasing maximum flow.

Will it suit my Nissan Patrol GU?

It's listed to fit the Nissan Patrol GU with the 4.5L engine. The GU ran for a long production life with several updates, so confirm your exact build with the workshop — the listing is a guide, not a confirmed fit on its own.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits this cat-back in-house across the Illawarra. Because it keeps the factory catalytic converter, the emissions equipment stays as it left the factory; we confirm clearances and hanger points on the GU body before booking you in.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
